Background. The COVID-19 pandemic, which swept the world in 2020–2021, had a significant impact on the epidemiological picture of hematological malignancies. Aim. To study the dynamics of epidemiological indicators of five chronic hemoblastoses in Moscow over a 12-year period, and also to assess the impact of the COVID-19 pandemic on these indicators. Materials and methods. A population-based study was conducted for five types of oncohematological diseases: multiple myeloma, Hodgkin's lymphoma, follicular lymphoma, chronic lymphocytic leukemia, chronic myeloid leukemia. The annual rates of morbidity, mortality, prevalence of these nosologies, overall survival, and expected overall survival were calculated. Gender and age characteristics for each disease were determined. Results and discussion. The present study showed a uniform increase in the incidence and prevalence of five hematological malignancies between 2012 and 2019. Convincing evidence of an increase in mortality and a decrease in the number of diagnosed cases in comparison with the expected figures for these hematological malignancies in 2020–2021 was presented. A greater reduction was shown for cases diagnosed at early stages compared to later ones. During the pandemic, a significant increase in mortality was recorded among patients with chronic lymphocytic leukemia and multiple myeloma, while in cohorts of patients with chronic myeloid leukemia and Hodgkin lymphoma it increased slightly. The return of morbidity, mortality and prevalence rates to the original dynamics in 2022–2023 has been demonstrated. Conclusion. This study demonstrated the features of the regional pattern of incidence, mortality, prevalence and gender-age characteristics of five hematological malignancies and provided the changes in the indicators dynamics of different hematological malignancies during the COVID-19 pandemic.
